Thanks for that info fella's. I'd take them spare shafts but the freight to australia might defeat the exercise,not to mention exchange rate . Thought those vanes would be annoying. Going to start on shafts shortly. Interesting about kirby does your R60 have chopper.I have'nt so Aus$6000 for kirby might be to much to spend for a rear axle weight they've obviously had some experience.My wheat straw seems to always measure ten to twelve inches i would,nt really call that to long i'm pretty sure rotarys grind,shorten straw pretty well compared to conventional's. There's not much left of canola stalks either H'mmmmIJ. Or are they talking about volume of stuff cause does seem to be lot of stuff (depending on cutting height) coming out of that chute at a quick rate in a narrow band. talking of banging ya head up the back of combine on my N5 you sort of have to bend and twist ya self under and then up to get in behind chaffer to have a look around,adjust .because of that back plate thing that directs expelled chaff(note no grain haha)sort of down and out at 45 degree's. Was thinking about removing that plate but then watching combine operate (rarely) could see that stuff and dust was like rooster tailing and sort of being flung down and away from machine which would only be good for air filters radiator etc. So would removing that plate stop that from happening so stuff would be more inclined to go where you dont want it particuarly on windy days like all up around engine. I should try it only a few bolts holding it in or has someone try'd it or should i stop thinking about these things and go and turn the tv onIJ thanks peng.
